  • Starlight Instruments 2.0" Adapter for Takahashi CN212 and MEWLON 180, 210 and 250mm Telescopes

    The Starlight Instruments 2.0" Adapter creates the essential 71x1mm female thread connection for mounting a Feather Touch focuser onto Takahashi CN212, Mewlon 180, Mewlon 210, and Mewlon 250 telescopes. Its precise 1.0" length ensures correct spacing, allowing you to achieve sharp focus with your upgraded 2.0" focuser.

    Upgrade to a 2.0" Feather Touch: The 71x1mm Solution for Takahashi Scopes

    This adapter is the key to unlocking the full imaging potential of your Takahashi telescope by enabling the installation of a Starlight Instruments 2.0" Feather Touch focuser. While Takahashi optics are world-class, this upgrade replaces the stock focuser with the zero-shift, dual-speed precision required for critical astrophotography and demanding visual observation.

    Machined to exact tolerances, the adapter threads directly onto the telescope's rear cell, presenting the correct interface for a 2.0" Feather Touch. This solid, secure connection eliminates any potential for flexure, even with heavy cameras or accessory loads. Note that this adapter configuration does not provide enough back focus to work with a binoviewer.

    • Direct Takahashi Fit: Specifically designed for the 71x1mm rear cell thread of the Takahashi CN212 and Mewlon 180, 210, and 250 models.
    • Enables Feather Touch Upgrade: Allows you to replace the standard focuser with a 2.0" Feather Touch, gaining ultra-fine focus control and robust load-bearing capacity.
    • Secure Mechanical Connection: The precisely cut 71x1mm thread ensures a rigid, non-flexing link between your premium optics and your new focuser.
    • Important Limitation: This adapter and a 2.0" focuser will not reach focus with a binoviewer due to insufficient back focus.

  • Which Starlight Instruments focuser does this 2.0" Takahashi adapter work with?

    This adapter is designed to connect any Starlight Instruments 2.0" focuser, such as the FTF20 series Feather Touch Crayford or Rack and Pinion models, to the specified Takahashi telescopes.

    Why would I replace the stock focuser on my Takahashi Mewlon 210 with this adapter and a Feather Touch?

    Upgrading your Mewlon 210 with this adapter and a 2.0" Feather Touch focuser provides significant advantages for astrophotography. The Feather Touch offers zero image-shift, ultra-fine 10:1 focusing, and a higher load capacity, which are critical for achieving perfectly sharp stars with modern imaging cameras.

    Is installing this Starlight Instruments 2.0" adapter on a Takahashi CN212 difficult?

    Installation is straightforward. You typically unthread the stock focuser assembly from the telescope's 71x1mm rear cell thread, then carefully thread this adapter in its place. The 2.0" Feather Touch focuser then attaches to the adapter.

    The description says this adapter won't work with a binoviewer on my Mewlon 250. Why is that?

    Binoviewers require a significant amount of inward focus travel (back focus). The combined length of this 1.0" adapter and a 2.0" Feather Touch focuser consumes too much of the Mewlon 250's available back focus, preventing the optical path from being short enough to reach focus with a binoviewer.

    How do I confirm this adapter has the correct 71x1mm thread for my Takahashi telescope?

    The 71x1mm thread is the standard rear port thread for the Takahashi CN212, Mewlon 180, Mewlon 210, and Mewlon 250 telescopes. If you have one of these models, this adapter is the correct fit for attaching a 2.0" Starlight Instruments focuser.

    What is the benefit of the 1.0" length of this Starlight Instruments adapter?

    The 1.0" length is engineered to place the 2.0" Feather Touch focuser at the correct distance from the telescope's rear cell. This ensures the focuser has adequate travel range to achieve sharp focus with a wide variety of standard eyepieces and cameras.
